The Pythagorean Theorem states that a^2 + b^2 = c^2 with a and b being lengths of legs and c being the length of a hypotenuse. So we can use our givens to solve for the remaining leg.
9^2 + b^2 = 15^2
81 + b^2 = 225
b^2 = 144
b = 12

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.
We are given that grocery store sells a bag of 7 oranges for $4.48. If Khloe spent $6.40 on oranges, then
We have to do as $4.48 divide by 7
4.48 / 7 = $0.46
Therefore, Each orange costs $0.64
For 10 oranges;
$0.46 x 10 = $6.40

Each month Marla pays a $30 cell phone bill from her bank account. At the
end of one year, what is the change in the amount of money in Marla's account
because of her cell phone bill? Write a multiplication equation to represent the
problem. Explain what the product represents.
Answer:
-$360.00 change
Step-by-step explanation:
Now there is either some information missing, like her starting total in the bank; or they want you to explain the net change. But the way the question is worded it is stating she is paying $30 over 12 months. This means she has paid $360.00 in that 12 months aka 1 year. Her bank account should have had a balance. So you could technically say B for balance. B-30*12. To get your answer. Although there are many ways to write an equation expression of this question. If you know the starting balance then it's better. But you could assume her starting balance was $0. Which would be 0-30M*12 where M could represent monthly. And the same answer would occur of 360. Is there more information?
30*12= X (x equals the total paid)
X-30*12 (if x is her balance before paying any money)

Answer:
1 meter = 100 cm
6 meters = 600 cm
600 x 3 = 1800 cm
Given that a = 15 cm and b = 8 cm, work out x
Answer:
the value of x is 17 cm
Step-by-step explanation:
The computation of x is shown below:
Here we applied the pythagoreans theorem
x^2 = a^2 + b^2
x^2 = 15^2 + 8^2
X^2 = 225 + 64
x^2 = 289
x = sqrt(289)
= 17
Hence, the value of x is 17 cm

The ratio of teachers to students in a particular school is 1 to 11. The ratio of female students to the total number of students is 4 to 9. If there are 396 female students, then how many teachers are there?
Answer:
81
Step-by-step explanation:
Set up a proportion to find how many total students there are [notice how females are on top and totals are on the bottom of the ratios]
[tex]\frac{4}{9}[/tex] = [tex]\frac{396}{x}[/tex] so cross multiply 4x = 396(9) so x = 891, if there are a total of 891 students and you need 1 teacher per 11 students then take 891/11 so you need 81 teachers.
You could set up another proportion 1/11 = x/891
If there are 396 female students, there are 81 teachers.
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.
Thus, a = px, b = qx
First, Set up a proportion to find how many total students there are
[notice how females are on top and totals are on the bottom of the ratios]
So, 4/9 = 396 / x
then, cross multiply
4x = 396(9)
so x = 891,
if there are a total of 891 students and we need 1 teacher per 11 students then take 891/11.
Thus, you need 81 teachers.
Also, we could set up another proportion 1/11 = x/891
Hence, If there are 396 female students, there are 81 teachers.

Answer:
26
Step-by-step explanation:
m + 5q | Given
1 + 5(5) | Substitute the values
1 + 25 | Distribute (5(5) is the same as writing 5 × 5
26
The solution of m + 5q is 26, where m = 1, and q = 5.
What is expression?Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation : Divides left hand operand by right hand operand
For example 4/2 = 2
Given expression as :
⇒ m + 5q
where m = 1, and q = 5
Substitute the values of m = 1, and q = 5 in the expression and apply the arithmetic operations
⇒ 1 + 5(5)
⇒ 1 + 25
⇒ 26
Hence, the solution of m + 5q is 26, where m = 1, and q = 5.

Answer:
see explanation
Step-by-step explanation:
Using the cofunction identity
sec(90 - x)° = cscx° , then
7A = 90 - 5A ( add 5A to both sides )
12A = 90° ( divide both sides by 12 )
A = 7.5°

Step-by-step explanation:
(x + 2) ÷ 2 + (x + 4) ÷ 4 = 4
lcm is 6
(x + 2) ÷ 2 × 6 + (x + 4) ÷ 3 × 6 = 4
(x + 2) × 3 + ( x + 4) × 2 = 4
3x + 6 + 2x + 8 = 4
correct like terms
3x + 2x + 6 + 8 = 4
5x + 14 = 4
5x + 14 - 14 = 4 - 14
5x = - 10
5x ÷ 5 = -10 ÷ 5
